Key Features

• AntiGravity Suspension System – Delivers a comfortable, body-contoured carry by distributing weight evenly across the back and hips, reducing pressure points and improving balance on uneven terrain. The suspended mesh backpanel promotes airflow, helping to keep you cooler during long, strenuous hikes.
• Fit-on-the-Fly Hipbelt – Allows for precise, on-the-go adjustments to accommodate different body sizes and load distributions, ensuring a secure and personalized fit throughout your hike. This feature is especially helpful when layering clothing or redistributing weight mid-trail.
• Adjustable Backpanel Torso System – Features an intuitive ladder-style adjustment mechanism that lets you customize the torso length for optimal weight transfer and comfort. The system makes it easy to fine-tune the fit before setting out, ensuring the pack sits properly on your frame for maximum efficiency.
• Integrated Raincover – Built-in waterproof cover deploys quickly to protect your gear from rain, snow, and moisture, eliminating the need to carry a separate rain cover. Stored in the bottom compartment, it’s always on hand when weather turns unexpectedly.
• Side Panel Zip Access – Enables direct access to the main compartment from the side, making it easy to retrieve items like a jacket, food, or electronics without unpacking the entire bag. This is especially useful when your pack is fully loaded and anchored to a rock or tree.
• Floating Top Lid – Adjustable lid increases pack volume when needed or can be removed entirely to reduce weight and streamline the pack for shorter trips. When detached, it can double as a small daypack or summit bag.
• Reinforced Shove-It Pocket – A durable front stash pocket with fabric reinforcement holds layers, snacks, or gear you need quick access to, even when the pack is full. The stretchy mesh design expands to accommodate bulky items while maintaining a low profile.
• Internal Hydration Sleeve with Exit Port – Accommodates a hydration reservoir (sold separately) with a centered back exit port for convenient hose routing and easy drinking on the trail. The sleeve is positioned to keep the reservoir stable and centered for balanced weight distribution.
• Lightweight, Streamlined Build – Thoughtfully designed to remove excess weight while retaining core performance features, ideal for hikers prioritizing efficiency without compromise. Every component is evaluated for necessity, ensuring nothing unnecessary adds bulk or weight.
• Eco-Conscious Materials – Constructed with bluesign APPROVED recycled main body fabrics, supporting sustainable production practices and long-term durability. These materials meet strict environmental and safety standards throughout the supply chain.

Important Notes

This pack is designed for men and sized for torso lengths in the L/XL range. The hydration reservoir is not included and must be purchased separately. Always adjust the torso length and hipbelt before loading to ensure optimal fit and comfort. The integrated raincover is stored in the bottom compartment and should be deployed in wet conditions to protect contents. Regular cleaning with mild soap and water is recommended to maintain fabric performance and longevity. Avoid machine washing or dry cleaning to preserve the integrity of the materials and coatings.
